Abstract:
Surge is an unstable operating mode of a compression system that occurs at mass flows below the so-called surge line. The instability is characterized by large limit cycle oscillations in compressor flow and pressure rise that reduce compressor performance.
The paper described the dynamic behavior of centrifugal compressors. Then the compression system model is used to design an active surge control system.
The developed surge control system was implemented on MATLAB-SIMULINK program with data of Solar Compressor in SIRT Oil Co. and presented in a simple form.
